Android onConfigurationChanged not being called
I am having trouble with telling Android to not call onCreate()
when the orientation changes. I have added android:configChanges="orientation"
to my manifest but still when the orientation changes onCreate()
is called. Here is my code.
AndroidManifest.xml
<activity android:name="SearchMenuActivity" android:theme="@android:style/Theme.NoTitleBar" android:configChanges="orientation"></activity>
SearchMenuActivity.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set the current layout to the search_menu
setContentView(R.layout.search_menu_activity);
Log.d(TAG, "onCreate() Called");
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
//don't reload the current page when the orientation is changed
Log.d(TAG, "onConfigurationChanged() Called");
super.onConfigurationChanged(newConfig);
}
And my LogCat Output
06-23 12:33:20.327: DEBUG/APP(2905): onCreate() Called
//Orientation Changes
06-23 12:33:23.842: DEBUG/APP(2905): onCreate() Called
Does anyone know what I am doing wrong? Thanks.
This was my gremlin for the ~same problem:
Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must decalare android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).
(From http://developer.android.com/guide/topics/resources/runtime-changes.html)
TL;DR: add "|screenSize" to android:configChanges="orientation" for API 14+
A couple of things to try:
android:configChanges="orientation|keyboardHidden|screenSize"
rather than android:configChanges="orientation"
Ensure that you are not calling setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
anywhere. This will cause onConfigurationChange() to not fire.
Check that you are not using android:screenOrientation
in your manifest.
If none of that works, read through the Android doc on handling runtime changes and make sure you are doing everything correctly. There may be something somewhere else in your code that's causing the problem. http://developer.android.com/guide/topics/resources/runtime-changes.html
EDIT: As derrik pointed out, I assumed that you were changing the configuration with the accelerometer detecting what way the device was facing. If you want the configuration to change as the keyboard is shown/hidden the configChanges in the manifest must include keyboardHidden
as well.
Try use this one.....
android:configChanges="orientation|keyboardHidden|screenSize"
You should change the configChanges entry in AndroidManifest.xml to:
android:configChanges="keyboardHidden|orientation"
Otherwise, sliding the keyboard doesn't trigger onConfigurationChange() even though the orientation changes. I just tested this on my HTC Desire Z.
